Description
Technical field
the utility model relates to a kind of boiler flue gas desulfurization system, belongs to environmental technology field.
Background technology
boiler is a kind of energy conversion, and the energy to boiler input has chemical energy, electric energy in fuel, and boiler exports steam, high-temperature water or the organic heat carrier with certain heat energy.The original meaning of pot refers to the water container heated on fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.The hot water produced in boiler or steam directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator, mechanical energy are converted to electric energy again.Because the burning cost of coal is lower, China's most enterprises still adopts traditional coal as boiler oil.But coal can produce more sulfide in combustion, directly discharge will certainly cause immeasurable pollution to environment.So country is all set with discharge standard to the discharge of boiler smoke at present.And existing a lot of desulphurization plant (dry method or wet method) is not that cost is too high, is exactly that desulfurization is off quality, cannot enterprise demand be met.
Utility model content
the purpose of this utility model is, provides a kind of boiler flue gas desulfurization system.Its equipment cost is relatively low, and desulfurization and dedusting is more thorough.
the technical solution of the utility model: a kind of boiler flue gas desulfurization system, be characterized in: comprise the pretreatment chamber be connected with boiler by first row smoke pipe, be provided with blower fan in pretreatment chamber to be connected with second row smoke pipe, the gas outlet of second row smoke pipe is connected to the distribution interlayer of desulfurizing tower, distribution interlayer is evenly equipped with multiplely emit tracheae; Also be provided with the filter plate be positioned at above distribution interlayer in desulfurizing tower, the gas outlet at desulfurizing tower top is connected with chimney by the 3rd smoke exhaust pipe, and is also provided with the spray nozzle be positioned at below gas outlet in desulfurizing tower.
in above-mentioned boiler flue gas desulfurization system, described spray nozzle is connected to by shower and stores stock tank, and stores stock tank and be also communicated with desulfurizing tower by overflow pipe, and the overfall of overflow pipe is positioned at above filter plate.
in aforesaid boiler flue gas desulfurization system, be provided with chamber pretreatment chamber being separated into two the bottom connections in left and right in described pretreatment chamber, first row smoke pipe and second row smoke pipe are communicated to two different chambers respectively.
in aforesaid boiler flue gas desulfurization system, described in emit tracheal strips to be filled with gas stone.
in aforesaid boiler flue gas desulfurization system, bottom described desulfurizing tower, be provided with plasma discharge mouth.
compared with prior art, structure of the present utility model can utilize the tracheae that emits in desulfurizing tower to make boiler smoke form minute bubbles in desulfurization slurry, to increase the contact area of flue gas and desulfurization slurry, thus raising desulfurization degree, and the flue gas risen in the form of bubbles is through the broken refinement of filter plate gassing, further raising desulfurization degree, and desulfurizing tower top also once will spray process, and therefore desulfurized effect of the present utility model is very remarkable.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
mark in accompanying drawing: 1-boiler, 2-first row smoke pipe, 3-blower fan, 4-second row smoke pipe, 5-spray nozzle, 6-the 3rd smoke exhaust pipe, 7-chimney, 8-shower, 9-desulfurizing tower, 10-filter plate, 11-emits tracheae, and 12-stores stock tank, 13-overflow pipe, 14-distribution interlayer, 15-plasma discharge mouth, 16-dividing plate, 17-pretreatment chamber.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.A kind of boiler flue gas desulfurization system, as shown in Figure 1: comprise the pretreatment chamber 17 be connected with boiler 1 by first row smoke pipe 2, be provided with blower fan 3 in pretreatment chamber 17 to be connected with second row smoke pipe 4, the gas outlet of second row smoke pipe 4 is connected to the distribution interlayer 14 of desulfurizing tower 9, distribution interlayer 14 is evenly equipped with multiplely emit tracheae 11; Also be provided with the filter plate 10 be positioned at above distribution interlayer 14 in desulfurizing tower 9, the gas outlet at desulfurizing tower 9 top is connected with chimney 7 by the 3rd smoke exhaust pipe 6, and is also provided with the spray nozzle 5 be positioned at below gas outlet in desulfurizing tower 9.Described spray nozzle 5 is connected to by shower 8 and stores stock tank 12, and stores stock tank 12 and be also communicated with desulfurizing tower 9 by overflow pipe 13, and the overfall of overflow pipe 13 is positioned at above filter plate 10.Be provided with the dividing plate 16 pretreatment chamber 17 being separated into the chamber that bottom, two, left and right is communicated with in described pretreatment chamber 17, first row smoke pipe 2 and second row smoke pipe 4 are communicated to two different chambers respectively.Described emitting in tracheae 11 is filled with gas stone.Plasma discharge mouth 15 is provided with bottom described desulfurizing tower 9.
operation principle of the present utility model: the flue gas that boiler produces enters pretreatment chamber by first row smoke pipe; under spacer function; bulky grain ashes in flue gas fall to the bottom of pretreatment chamber; and sulfur-containing smoke gas enters in the distribution interlayer of desulfurizing tower under the effect of blower fan; then by haptoreaction abundant with slurries in the reacting slurry that emits tracheae to enter in desulfurizing tower with uniform bubble form; then through filter plate bubbles burst aggravation reaction, the flue gas finally rising to top also can be undertaken just entering smoke stack emission after spray processes by spray nozzle.And in desulfurizing tower, be also provided with overflow pipe, when the certain altitude that the liquid level in desulfurizing tower is raised, slurries meeting overflow is to storing stock tank, and slurries required when spraying also are obtain from storing stock tank.When desulphurization reaction proceeds to a certain degree, can form a lot of sediment bottom desulfurizing tower, the plasma discharge mouth now can opening bottom discharges.When in slurries, reactant concentration is inadequate, can store in stock tank carry out interpolation regulate, really realize dynamic circulation.
